IUBS
Backer Free Metal Web Joist Hanger (with adjustable skew)
The IUBS solves the problem of skewed hangers for metal web to metal web
connections. It can be handed left or right on site, by the carpenter, removing
confusion when the floor is built opposite to the drawing.
The IUBS is fully adjustable from 5° to 67.5° degrees skew, reducing the need
for “special” skew hangers.
- Standard 45° skew, with site adjustable skew from 5° to 67.5° degrees.
- Non-handed hanger, can be left or right skewed - adjusted on site removing any handing confusion and reduce stocking.
- Use SDS25212 for enhanced download capacity.
- Can be used on metal web joist or solid joist headers.
- Optional nail holes for additional download.

Step 1: Position the back plate onto the header in the required position.
Step 2: Secure the back plate (inside angle) with the specified nails.
Step 4: Secure the obtuse side of the back plate onto the header with all the specified nails, ensuring the face of the back plate is tight against the header.
Step 5: Offer the stirrup to the back plate ensuring it is located on the correct side (which can be either left or right hand side). Once all of the hooks (on the back plate) are clearly through the apertures (on stirrup) slide in a downward direction ensuring all hooks engage onto the stirrup and click into position.
